How to do math on Array elements?

[Kicks.Spin]

I made an Array called myRangeArray[47] with 48 slots- one for each 30 minute TPO time period. I used Date.Time conditionals to store range values for 1/2 hour bars ending at 1:30am 013000 in myRangeArray[2] slot 2 for example. So i have right data in right place. But my question is how can i take the average of all numbers in slot [2]? How can 2 std deviation be calced? In short, how can a person do math on the list of doubles in a slot? thanks!

Hi Kicks.Spin, thanks for posting.

I found several links through a google search on taking the average of a C# array here (publicly available):

I don't fully understand what you're doing but, I recommend this library which I use a lot:

https://numerics.mathdotnet.com/DescriptiveStatistics.html

Statistics.Mean(slot[2])
Statistics.PopulationStandardDeviation(slot[2]) * 2

might be what you need
